OpenAI released GPT-6 Sol, for complex work like coding, and GPT-6 Luna, for high-volume summarization and extraction, with API pricing roughly half the 5.6-series models. The company claims Sol makes about half as many mistakes as its predecessor and reaches Astra-level reliability at much lower cost. Rollout spans ChatGPT Work, Codex, and the API, with Luna also coming to desktop and free tiers.

Why it matters

OpenAI's mid-tier price collapse lands within hours of Anthropic's Opus 5.5 cut, signalling an intensified frontier price war.
